Figure 6.
Figure 6 A MADIR approach with data from the S. cerevisiae ALAD lead acetate co-crystal allowed the calculation of an electron-density map at 3.0 Å resolution in which there was a clear solvent boundary. The map was extended to show the overall organization of the octamer. Here, four subunits of the ALAD octamer can be seen disposed around the crystallographic fourfold axis.
